IntroductionForces and motions are the elements utilized by mechan-ical equipment to perform work. Unfortunately, these same elements can produce undesirable effects, even in the most carefully designed equipment. The adverse effects of vibration, shock and noise disturbances range from simple annoyances to shortened equipment life through failure of its components. They will affect comfort, safety or performance.

Vibration, shock and noise control components, prop-erly applied, will improve your products. They will operate more smoothly and quietly, and they will be less disturbing to surrounding equipment and personnel, less susceptible to damage and less expensive to make. Bonded rubber mounts provide cost-effective solutions to problems involving vibration, shock and structural noise control.

The theory and concepts for bonded rubber mounts are relatively straightforward. A great many of the applica-tions are uncomplicated, and the nonspecialist can handle them directly. However, some vibration and shock control problems are quite complex, making component selection and design complicated.

These applications require the involvement of special-ists in order to arrive at suitable recommendations, and LORD has a technical staff available to assist you. In any event, the information presented in this catalog will prove useful in your independent application solutions, as well as at those times when technical assistance is necessary. Refer to Engineering Guide, Application Selection Guide section.

This catalog has been prepared to assist the individual who does not frequently deal with vibration and shock problems and to remind others of the versatility of bonded rubber mounts. It presents the important infor-mation needed to select and use bonded rubber mounts: terms and defi nitions; theory; sample problems; and data on standard mounts.

Terms and Defi nitionsThere are a number of terms which should be understood before entering into a discussion of vibration and shock theory. Some of these are quite basic and may be familiar to the users of this catalog. However, a common under-standing should exist for maximum effectiveness.

Acceleration – rate of change of velocity with time. Usually along a specifi ed axis, usually expressed in “G” or gravitational units. It may refer to angular motion.

Amplitude – the maximum displacement from its zero value position.

Compression – when specifi ed as a direction for loading – a deformation caused by squeezing the layers of an object in a direction perpendicular to the layers.

Damping (c) – the mechanism in an isolation system which dissipates a signifi cant amount of energy. This mechanism is important in controlling resonance in vibratory systems.

Disturbing Frequency (fd) – the number of oscilla-tions per unit time of an external force or displacement applied to a vibrating system. fd = disturbing frequency.

Durometer (hardness) – an arbitrary numerical value, which measures the resistance to the penetration of the durometer meter indenter point; value may be taken immediately or after a very short specifi ed time.

Fragility – is the highest vibration or shock level that can be withstood without equipment failure.

“G” Level – an expression of the vibration shock accel-eration level being imposed on a piece of equipment as a dimensionless factor times the acceleration due to gravity.

Isolation – the protection of equipment from vibration and/or shock. The degree (or percentage) of isolation necessary is a function of the fragility of the equipment.

Load Defl ection Curve – the measured and recorded displacement of a mounting plotted versus an applied load.


Page 4 of 124

Natural Frequency (fn) – the number of cycles (expressed as Hertz or cycles per second) at which a structure will oscillate if disturbed by some force and allowed to come to rest without any further outside infl uence.

Random Vibration – non-sinusoidal vibration character-ized by the excitation of a broad band of frequencies at random levels simultaneously.

Resonance – vibratory system is said to be operating at resonance when the frequency of the disturbance (vibration or shock) coincides with the system natural frequency.

Set – is the amount of deformation never recovered after removal of a load. It may be in shear or compression.

Shear – when specifi ed as a direction for loading – a deformation caused by sliding layers of an object past each other in a direction parallel to the layers.

Shock Pulse – a shock pulse is a transmission of kinetic energy to a system, which takes place in a relatively short length of time compared to the natural period of this system. It is followed by a natural decay of the oscillatory motion. Shock pulses are usually displayed as plots of acceleration vs. period of time.

Spring Rate – is the force required to induce a unit defl ection of spring. A steel spring has a very linear relationship between force and defl ection. Elastomeric springs may or may not be linear depending on the amount of defl ection due to the load.

Static Defl ection (ds) – the defl ection of the isolator under the static or deadweight load of the mounted equipment.

Transmissibility (T) – is a dimensionless unit expressing the ratio of the response vibration output to the input condition. It may be measured as motion, force, velocity or acceleration.

TheoryVibration is an oscillatory motion. Any body with mass and elasticity can vibrate. The simplest type of vibrating system is called a single-degree-of-freedom spring-mass system. The spring is characterized by its spring rate, K, and a mass, M.

This system is called a single-degree-of-freedom system because motion can occur in only one direction. Spring rate defi nes the force required to induce a unit defl ec-tion of a spring. A steel spring has a linear relationship between force and defl ection. Elastomeric springs may or may not be linear depending on the amount and direc-tion of the load. Nonlinearity can be designed into elas-tomeric springs to achieve certain results. Elastomeric springs also differ from steel springs in that their stiffness is sensitive to the rate or speed of defl ection. If a rubber spring is defl ected quickly, it appears stiffer than if it is defl ected slowly.

When a mass is attached to a spring, the mass moves to its position of equilibrium, position 1. The difference between the spring’s undefl ected or free length and its position of equilibrium is called the system’s static defl ection, ds. If a force is applied to the system, posi-tion 2, and then removed, the spring-mass system will vibrate, position 3. When plotted against time, the position of the mass relative to its equilibrium position is a sinusoidal curve. The maximum single amplitude is the defl ection of the mass from its equilibrium position to its maximum displacement in one direction. Double amplitude displacement is the total defl ection in both directions. The period of vibration is the time it takes for the mass to move from its equilibrium position to its peak in one direction, to its peak in the other and back to its equilibrium position.

Figure 1

If a load is applied to our spring mass system and then released, the mass will vibrate at a constant rate. We call this condition resonance, and the vibration rate is called the natural or resonant frequency. The natural frequency of a system can be considered a function of mass (M) and spring rate (K).

Natural frequency is usually measured in hertz. This equation can be written in many forms:

where K=spring rate, lb/in; W=weight in pounds; M=mass in lb-sec2/in; and g=acceleration of gravity, 386.2 in/sec2. From this formula, you can see that an increase in mounting system stiffness or a decrease in weight will increase the natural frequency. A decrease in mounting system stiffness or an increase in weight will decrease the natural frequency.

So far we have discussed free vibration, what happens when a force is applied and removed from our spring mass system. When a force is applied to the system as a sinusoidal vibration, the output through the system can be defi ned in terms of transmissibility. Transmissibility is the ratio of output to input and is dimensionless. Vibra-tion output and input can be measured as motion, force, velocity or acceleration. The transmissibility of a mount is a function of the relationship of the input frequency to the natural frequency and the amount of damping.

for undamped springs when fd/fn ≥ √2 where fd=input or disturbing frequency and fn= natural frequency.

In Figure 1, we see transmissibility plotted against the frequency ratio, fd/fn. When the disturbing frequency is very low compared to the natural frequency, the trans-missibility is close to one, position 1. If the disturbing frequency is close to the natural frequency, the transmis-sibility is very high. The output is much larger than the input. (See Region of Amplifi cation, position 2.) Position 3 is the crossover point when the fd/fn ratio is equal to the √2. When the disturbing frequency is high compared to the natural frequency, transmissibility is low. (See Region of Isolation, position 4.) Isolation is the goal of an elasto-meric spring. We wish to attenuate a known disturbing frequency. From the desired transmissibility, we can defi ne the required frequency ratio and calculate the system natural frequency. Using the natural frequency calculations, we can calculate the required spring rates for the vibration mounts.

An elastomeric spring has another characteristic that a simple steel spring does not. It has hysteresis damping, C.

When an elastomeric mount is defl ected, some energy is converted to heat. Without damping, a spring mass system will continue to oscillate at its resonant frequency for an extended time after the input has stopped. With damping, the oscillations decay more quickly. Damping also has an effect on transmissibility.

ENGINEERING GUIDE


Page 6 of 124

Figure 2 is a plot of transmissibility for two levels of damping, . As you can see, the greater the amount of damping, the lower the transmissibility at resonance, position 1. Positions 2a and 2b have different transmis-sibility values for the same frequency ratio when using different values for damping. This illustrates the compro-mise an engineer must make when choosing the neces-sary amount of damping in an elastomeric mount. If the disturbing frequencies are known, we would design a lightly damped mounting system with a natural frequency well below the disturbing frequency. The low damping would provide optimum isolation. In cases where the disturbing frequencies are numerous, unknown or impos-sible to avoid, a highly damped system is preferred. The high damping reduces the peak response that can occur if the same disturbances are near the natural frequency of the mounts. A reduction in isolation effi ciency will also occur. Vibration isolation employs resilient mountings and mounting systems to reduce the transmission of vibration from one point to another. All simple or single-degree-of-freedom problems can be classifi ed into two groups:

1. Mass excited system: Protecting the supporting struc-ture from vibratory disturbances originating in the supported mass.

2. Base Excited System: Protecting the supported mass from the vibratory disturbances of the supporting structure.

In the fi rst case, mass excited, the mass moves because of the vibrating force. This causes a defl ection across the spring which transmits a force to the structure. This force must be reduced. In the second case, base excited, the vibrating or moving structure causes a defl ection across the spring which transmits a force to the supported mass. This causes the mass to move. This motion must be reduced.

When do you start thinking about vibration control? The earlier the better. The record proves that the best time to consider the need for vibration control is in the beginning stages of product design.

The reward for this kind of foresight is best performance at the lowest cost. Your best chance of gaining this benefi t comes when you call in a specialist as soon as the vibration or shock problem is recognized. Recog-nizing such a problem is a design responsibility. Vibra-tion analysis is a requisite of equal importance with stress analysis, cost analysis, material selection and reliability assurance. No design is complete without all of these.

These benefi ts are produced when the mounting system design coincides with product design:

• Accurate analysis of the dynamic environment.• Precise determination of mounting system

requirements.• Most advantageous system confi guration.• Adequate space for mountings and sway space

clearance for the mounted assembly.• Predictable results through application of proven prin-

ciples to meet exact requirements.

Figure 2



These are just a few of the reasons for considering vibration control early in design. It is apparent that the designer has everything to gain and nothing to lose by following this practice.

Shock MechanicsShock is a common phenomenon with many familiar sources: aircraft landings, impacting of railroad cars, power surges or impacts in marine drive systems, driving over bumps, dropping product containers, explosions, missile launching and staging. Thus, shock protection is a common requirement in good product design. Today’s trend to higher speeds, heavier loads, larger power plants and lighter weights accentuate the problem.

Mechanical shock is a nonperiodic disturbance of a mechanical system characterized by suddenness and severity. Such extreme disturbances cause signifi cant forces in the system which may be damaging. A shock input is non-repetitive in nature and of limited time dura-tion. The response it produces normally decays to an arbitrarily small value before the next disturbance.

Shock inputs may be caused by:

1. A sudden introduction of energy into the system or a change in the level of energy in the system.

2. A force excitation.3. An abrupt motion, velocity or acceleration change.

Analysis of a shock problem usually starts with an examination of the shock input. Shock inputs are of short duration and non-periodic. Often these short duration transient loads have complex wave shapes. Analysis may be simplifi ed by comparing the actual wave shape to several simple wave shapes for which the response is known. Important features of the shock pulse are: maximum amplitude, time duration and approximate shape. The majority of excitations typically encountered are:

• Half-sine Shock Pulse• Triangular Shock Pulse• Drop Shock• Velocity Shock

Each can be defi ned as:

• Half-sine Shock Pulse

• Triangular Shock Pulse

• Drop Shock


Page 8 of 124

• Velocity Shock

where: V = change in velocity, in/sec g = acceleration due to gravity, 386 in/sec2 Gin = shock pulse magnitude, G’s = 3.1416 to = shock pulse duration in seconds h = drop height in inches V2 = velocity at point 2 V1 = velocity at point 1

Engineers should consider mechanical shock by com-paring the fragility level of the most sensitive component to the actual shock acceleration input. Fragility is defi ned as the highest acceleration level beyond which equip-ment will fail to operate within specifi cation. The shock mount shall not permit the output acceleration to exceed the fragility level. The G’s output can be calculated by:

In other words, the input acceleration is absorbed by the resilient mount, and the shock energy is released over a broader time base. By dispersing the shock energy over a broader time base, the output accelerations are reduced.

The elastomeric isolator must have the ability to accommodate the higher defl ections that are characteristic of mechanical shock. The dynamic defl ection, dd, can be calculated by:

This dynamic defl ection must not exceed the safe limits of the isolator’s strain capability. We can use an equation to determine the minimum rubber wall thickness for a shear or sandwich mount:

The designer must also accommodate sway space within the product design. If not, even though the shock mount may be very effi cient, lack of necessary sway space may cause secondary collisions resulting in the same damaging effect as if no shock attenuation devices were used.

If the concepts outlined above are kept fi rmly in mind, the designer will be well on his way to the most effi cient attenuation of shock in a wide variety of applications.

Elastomers for Vibration Isolation“Rubber” is a synthetic or natural material whose long-coiled, high molecular weight chains have been cross bridged by certain chemical ingredients to form a network. It is characterized by the ability to accept and recover from extreme deformation of 200% or more. The term “elastomer” includes natural rubber and the many synthetic materials that possess rubber-like properties.

Choice of an elastomer invariably hinges on the balance of properties offered. Some properties are interdependent, and the designer should understand the effect of one upon the other. To gain a desirable characteristic, for example, it may be necessary to accept reduction in some other property. Two or more optimum properties may be obtainable together.

Within the various families of LORD products, a number of elastomers may be selected. Some brief description may help guide in their selection for a particular problem.

1. The higher the density, the more rubber is required to make a given part. For example, compare neoprene and natural rubber. Even at the same price per pound, neoprene would be more expensive to use.

2. While tensile strength per se is not necessarily important, retention of strength at elevated temperatures suggests retention of other mechanical properties as well.

3. Abrasion-resistance ratings apply to a wide range of temperatures as well as type of abrasion (such as rubbing and impingement).

4. A high resistance to crack-growth indicates good general durability – necessary where physical abuse is expected.

5. Tear resistance, along with crack-grown resistance, is desirable where physical abuse is expected.

6. Rubbers that strain-crystallize at extreme deformations are much more durable in impact than those that do not. Low-temperature fl exibility also helps improve impact performance.

7. A high deformation capacity usually indicates a high fatigue resistance to fl exing.

8. The lower the permanent set, the better the structural integrity and the better the retention of initial dimensions.

9. The higher the resistance, the less the degradative heat buildup in a fl exing or dynamic situation.

10. The better the resistance to creep, the longer the life of the part, particularly where clearances are to be maintained.

11. Resistance to stress relaxation is essential in seals and other components under steady stress in service.

12. Good low-temperature fl exibility is a must for most shock absorbers. The fi rst jolt is critical, regardless of subsequent softness.

13. Resistance to oils and greases is essentially a surface effect: parts with poor resistance to these substances but that have appreciable bulk will not be degraded by such exposure.

Sample ProblemsExample Problem #1 – Vibration IsolationProblem: An electric motor and pump assembly, rigidly mounted on a common base, transmits vibration to other components of a hydraulic system. The weight of the assembly and base is 140 lb. Four isolators are to be located at the corners of the rectangular base. The lowest vibratory forcing frequency is 1800 rpm and is the result of rotational unbalance.

Objective: To reduce the amount of vibration transmitted to the supporting structure. A vibration isolation effi ciency of 70 to 90 percent is usually possible to obtain. Here a value of 80 percent is selected.

Solution:1. First fi nd transmissibility, T, which corresponds to the

required vibration isolation of 80 percent, (I = 0.8)

T + I = 1 or1 - I = T1 - 0.8 = 0.2 T = 0.2

2. Determine the forcing frequency fd in cycles per second (Hz). The lowest forcing frequency is used because this is the worst condition. If high isolation is attained at this frequency, isolation will be even better at higher frequencies.

3. Determine the natural frequency fn that the isolated system needs to provide a transmissibility T = 0.2. The following equation assumes zero damping.

4. Calculate the load at each mounting point. If the center of gravity of the supported mass is centrally located in the horizontal plane, simply divide the total weight by the number of mounting points.

140 lb ÷ 4 mounts = 35 lb/mounting point

5. Determine the required static defl ection and spring rate. Static defl ection (ds) for this natural frequency is calculated with the formula:

The required spring rate (K) can be calculated with the formula:

530 lb/in is the required spring rate for an isolator at a mounting point. This calculation can be completed using the total weight so the spring rate (K) calcu-lated will be a total spring rate rather than a per mount spring rate. Dividing by the number of mounts will equal a per mount spring rate.

6. Select a mount that has a maximum load rating equal to or greater than the supported point load and a spring rate equal to or smaller than the calculated value. For our example the load/mount is 35 lb, and the spring rate is 530 lb/in. We can select 4 pieces of part number 200P-35 which are rated at 35 lb with a spring rate of 560 lb/in. (Refer to Plateform Mounts, Table 1.)

7. Mounts are not always available with the right combi-nation of load capacity and spring rate. Overloading mounts is not recommended. Underloaded mounts will produce less static defl ection and not isolate as well. The Isolation Effi ciency Curve (in the following section) will help you determine the isolation effi -ciency you can expect. First calculate the static defl ection (ds) for the actual mount, 200P-35.



Check natural frequency:

Check isolation frequency:

Isolation Effi ciency I = 1 - T

I = 1 - 0.21 = 0.79

The isolation effi ciency of the 200P-35 is 79%.

Example Problem #2 - Shock IsolationProblem: An electronic component is subjected to an 11 millisecond, 1/2 sine, 20g input and must be isolated. The item’s fragility is 15 G’s. The weight of the component is 7 pounds and is supported at 4 mounting points.

Objective: Reduce the amount of shock transmitted through the frame to the electronic component.

Solution:

1. First calculate the change in velocity, V, for a 1/2 sine pulse.

2. Calculate the desired natural frequency. Fragility is 15 G’s, which is the desired G’s output.

3. Calculate the dynamic defl ection.

Isolation Effi ciency Curve for Flexible Mounting Systems

For simple linear vibration, the Isolation Effi ciency Curve illustrates the percentage of vibration isolation it’s possible to obtain in a fl exibly mounted assembly with any combination of static defl ection and disturbing frequencies. The bottom area shows the region of magnifi cation of vibration that occurs when the ratio of the disturbing frequency to the natural frequency of the mounted assembly is less than √2. A condition of reso-nance exists when the natural frequency of the assembly and the disturbing frequency are equal. The area illus-trates the percentage of the vibratory forces prevented from reaching the supporting structure when proper fl exible mountings are selected. Reduction in transfer of vibratory forces is obtained only when the ratio of the disturbing frequency to the natural frequency is greater than √2.

How to Use the Curve The curve can also be used to arrive at the required static defl ection by starting with the disturbing frequency. Find the point where the disturbing frequency and desired percent reduction in vibration line intersect. The vertical line passing through this point is the required static defl ection to produce the desired vibration isolation effi ciency of the disturbing frequency.

Fluidlastic™ MountsIntroducing a new generation of mounts. Fluidlastic™ Mounts combine rubber and fl uids to provide vibration isolation and noise reduction measurably better than conventional mounts. They also provide greater versatility because the mounts are tuned to precisely match appli-cation requirements. This new generation of mounts will help you solve tough vibration and noise problems.

Three-In-One PerformanceThe Fluidlastic Mount is three mounts in one depending upon the frequency and amplitude of the excitation. First, it’s a spring providing basic load and motion capability to the system. Second, it’s a damper providing restricted motion at or near resonant conditions. And thirdly, it’s a tuned absorber providing superior isolation at a specifi c frequency.

Fluidlastic Mounts are rubber mounts which encapsulate a fl uid that fl ows through a variety of ports and orifi ces depending upon the dynamic characteristics needed (see Figure 1). The result is a very versatile and effective vibration isolator.

Why They Out-Perform Conventional Rubber MountsThe Fluidlastic Mount concept allows the use of a softer mount for better isolation of vibration and uses internal fl uid damping to reduce motions at resonant condi-tions or shock inputs. Fluidlastic mounts offer tuneable damping. The level of damping and the frequency where the peak damping occurs can be specifi ed. A variety of fl uids and orifi ce confi gurations create this damper effect. The fl uid provides damping in the amplifi ca-tion region, as well as very low damping in the isolation region.

Another important feature of the Fluidlastic Mount is a conveniently packaged tuned absorber. Fluid move-ment within the mount as it is defl ected becomes a tuned mass at a specifi c frequency or frequency band. This absorber effect is accomplished by the porting and geometry of the fl uid path within the mount. The result is a dynamic stiffness that is considerably softer than the static stiffness for that frequency range. This feature is especially useful in improving isolation of noise or vibra-tion at a predominant frequency.

LORD Corporation’s design experience along with our test and analytical capability makes LORD the leader in the fi eld of a new generation of mounts. Contact LORD Engineering to review your job application requirements.

Machinery MountsFeaturing: Lattice Mounts Chan-L™ Mounts Industrial Shock Mounts Leveling Mounts

LORD Machinery Mounts are designed to support heavy equipment and isolate intermittent or continuous vibra-tion. The result is greater machine accuracy, longer service life, smoother operation and reduced mainte-nance. These mounts are available in four types to suit different needs.

Lattice Mounts are recommended for applications where disturbing frequencies are as low as 6 Hz. Their lattice design provides a soft vertical spring rate combined with lateral stability. Typical applications include shaker-screens, sifters, rubber mills, air compressors and large engines/generators.

Chan-L™ Mounts are recommended for machines where vertical disturbing frequencies are 600 cpm or higher. Their elastomer-supported channel design features a soft vertical spring rate. The design incorporates built-in protection against metal-to-metal bottoming. Typical applications include separating and grading screens and shakeouts.

Industrial Shock Mounts effi ciently control shock and structural noise transmission from heavy industrial machinery. Adjacent controls, sensitive instruments and precision machines are protected from impact distur-bances which could hamper their performance. Worker comfort is increased, and building structures need less maintenance.

Features and Benefi ts• High-effi ciency, multi-directional isolation of low

frequency vibration

• Extremely rugged and require no maintenance

• Easy to install

• Long service life

Surface-Effect MountsSurface-Effect Mounts combine surface-effect damping principles with traditional rubber-bonded-to-metal tech-nology. The result is a soft mount capable of providing effective damping over large defl ections and a wide range of frequencies. As cab and engine mounts in on- and off-highway vehicles, Surface-Effect Mounts meet the most demanding requirements for vibration isolation and noise attenuation while controlling motion.

The systems feature a damper pack containing an elastomer that comes in contact with a sliding surface, producing both hysteretic and friction damping. When conventional mounts are unable to satisfy vehicle requirements, Surface-Effect Mounts can successfully control noise and vibration for improved ride comfort and enhanced product performance and maintainability.

Features and Benefi ts• A smoothly damped response at low and medium

frequencies with isolation at high frequencies. Natural frequency is 6 Hz at rated load.

• Amplitude sensitive, responding to larger motions with greater damping forces

• Speed mount optimization and vehicle development by allowing easy in-the-fi eld adjustment of damping and small displacement decoupling

• Accommodate a wide range of rated loads

• Withstand R.O.P.S. loads with the addition of support rings. Further non-standard support rings for special applications are available.

• Offer optimal tuning through the modular spring/damper assembly for ride comfort and motion control

• Exhibit long, highly reliable service life

The on-site adjustable damping and decoupling capa-bilities of the mounts offer unique advantages in terms of reducing development/testing time and minimizing the cost of systems optimization. Adding or removing damping disks within a mount’s surface-effect pack changes the contact area and amount of damping for adjustment of prototype mounts.

Surface-Effect Mounts are simple in construction, and the absence of pressure seals and fl uids eliminates the possibility of leaks common with hydraulic mounts. In accelerated durability tests, these mounts have success-fully passed more than 11 million cycles (the equivalent of 3 million kilometers or 2 million miles of Class 8 truck cab service) without signifi cant wear.

Installation GuideSpecifi cationsMaterials: The elastomers are high quality natural rubber which meet LORD specifi cations (available upon request).

The elastomer-to-metal bonds are stronger than the elastomer.

Environmental: For applications in severe oil environ-ments, contact LORD. Based on extensive experience, center-bonded mounts have been designed to operate in normal fl uid, temperature and other environmental conditions such as found in the engine compartment of on- and off-highway applications.

Testing/Quality Control: Drawings of each part specify the load defl ection tests which are performed to assure consistency of spring rate characteristics.

Testing/Performance: Extensive laboratory fatigue testing has been performed under simulated service conditions.

InstallationInstallation is simple, consisting of four steps:

1. Both mount and socket should be lightly lubricated with rubber lubricant or water. A special rubber lubricant, P-80 Emulsion, is available from International Products Corporation; P.O. Box 70; Burlington, NJ 08016-0070; Phone: (609) 386-8770; Fax: (609) 386-8438.

2. Insert part in socket and rotate part by hand while applying axial force until partially positioned. Insert assembly driver in the metal inner member of the mount. Care should be taken that the driving device does not overhang the outside diameter of the inner member in order to prevent damage to the elastomer.

3. Apply pressure to the driving device to seat the mount in its socket.

4. Assemble the other elements of the support, insert the mount bolt and tighten to the required torque. When the nut is tightened against the snubbing washer, the rebound shoulder is formed auto-matically. The resulting pre-compression assures optimum performance.

BushingsFeaturing: Center-Bonded Bushings Square-Bonded Bushings

LORD Center-Bonded Bushings and Square-Bonded Bushings are used in applications where the absorption shock, attenuation of noise, reduction of wear and elimi-nation of lubrication is required.

Center-Bonded Bushings are designed to be loaded radially and utilize a soft torsional spring rate to provide freedom in rotation. High radial restraint maintains the alignment between joined parts. They are not intended for use where extreme rotational motion will occur. Typical applications include heavy duty highway equip-ment, drilling equipment, harvesters, combines and industrial machinery.

Square-Bonded Bushings accommodate angular move-ment and isolate vibratory disturbances in heavy equip-ment. These bushings combine a torsional spring with an elastomeric pivot and isolator. They provide positive torsional positioning and pivot action under the most demanding operating conditions. Typical applications include wheel suspensions, vibratory feeders, mobile power equipment and vibratory cable layers.

Easy to install, the uncomplicated designs of the Center-Bonded and Square-Bonded Bushings provide initial economy, while the rugged elastomers and high strength bonding assure extended service life.

Features and Benefi ts• Easy to install

• Uncomplicated design provides initial economy

• High-strength bonding assures extended service life

• Minimal maintenance due to specially compounded elastomer

To select a Square-Bonded Bushing for your requirements, compute the static torsional load it must support. Select from Tables 1-2, a bushing with static torque at 15° which is equal to or greater than the computed load.

Compute the static plus the dynamic torsional load. If this total load exceeds three times the static torque at 15°, select a larger size static torque rating part. Static radial load should also be computed and compared to the maximum static radial load listed above. Dynamic plus static radial load can also be three times loads listed above.

Installation GuideCenter-Bonded Bushing With Outer MemberClamp or press-fi t the outer member into a socket which has been machined to the dimensions shown on Center-Bonded Bushings with Outer Member – Table 1. The force required to install the joint in the socket with a press-fi t can be approximated from the formula:

Force (lb) = 2500 x diameter x length

The inner member is normally attached by clamping or bolting its extended ends to a mounting bracket. An alternate method would be to press-fi t a shaft through the inner tube.

Center-Bonded Bushing Without Outer MemberSince the outer part of this type joint is the fl exing element, it must be compressed and inserted directly into a socket which has been machined to the dimen-sions shown on Center-Bonded Bushings without Outer Member – Table 3. This is done with the aid of a funnel-shaped fi xture and a suitable lubricant: P-80 Rubber Emulsion Lubricant made by International Products Corporation; P. O. Box 70; Burlington, NJ 08016-0070; Phone: (609) 386-8770; Fax: (609) 386-8438.

The inner member attachment is accomplished in the same manner as described above for the joint with outer member.

Square-Bonded BushingsJoints may be installed in preformed sockets machined, cast or fabricated to dimensions as shown in Square-Bonded Bushings – Table 1.

Installation is a simple, four-step procedure:

1. Lubricate the mount and socket lightly with P-80 Rubber Emulsion Lubricant or water. Lubricant available from International Products Corporation; P. O. Box 70; Burlington, NJ 08016-0070; Phone:

(609) 386-8770; Fax: (609) 386-8438.2. Insert assembly fi xture or driving bolt through center

member. Take care that driving members do not over-hang center member outside diameter or damage may result to the elastomer.

3. Apply suffi cient pressure to seat the joint in the center of the supporting socket.

4. Attach the supported member snug against the center member.

Effi cient power transmission and driveline component durability are among powertrain designers’ most impor-tant concerns. Increased durability and up-time are two characteristics demanded by purchasers of today’s complex and expensive machinery. These demands can only be met with reliable, trouble-free, smooth-running powertrains free from damaging loads which compro-mise component life.

Powertrain component life is determined by the load spectrum each component will experience during the machine’s service life. Reciprocating engines, such as spark-ignited gasoline and compression-ignited diesels, produce alternating torque loads which, when super-imposed on the steady driving torque, create alter-nating stresses in driveline system components which shorten component life and reliability. High transient start-up torques and misalignment caused by skewed rotational axes between driver and driven in electric motor, hydraulic and pneumatic drives also cause high imposed forces on driven components. These unwanted forces loosen bolted joints and cause spline fretting, clutch disk wear, bearing failure, gear tooth fatigue and shaft fatigue, among an array of other problems.

Elastomeric fl exible couplings solve these problems. They prolong driveline component life because they reduce the magnitude of imposed loads, attenuate vibra-tion in multiple planes, accommodate misalignments in multiple planes, and act as barriers impeding noise created by meshing gears, engaging clutches, etc.

Elastomeric fl exible couplings are also maintenance-free. They require no lubrication or other maintenance throughout their service life. Among the large variety of coupling types available, LORD Corporation’s elasto-meric couplings offer the most comprehensive package of benefi ts available to the powertrain designer. LORD Corporation’s product lines include fi ve different elas-tomeric coupling styles which cover a wide range of application requirements.

ApplicationApplication requirements suggest the coupling style needed to optimize powertrain performance and component longevity. Misalignment accommodation, torsional vibration isolation, transient shock dissipation and required service life are important parameters to consider when selecting a coupling to fi ll specifi c application requirements.


LORD engineers can assist you with selecting an appro-priate coupling type and confi guration. With extensive analytical capability and years of experience in designing products for powertrain vibration, shock and motion control, LORD engineers offer everything from simple application assistance to complex system analysis and specialized product design.

Torsional vibration, transient shock and misalignment load analyses require specialized computer programs and engineering experience. LORD engineers can analyze your system and recommend the right solution, whether it’s a selection from the standard product line or a custom design.

• Hospital Bed – Actuator drive • Dynamometer – Driveline • Tachometer – Driveline • Pumps, Blowers, Compressors – Driveline

Features and Benefi ts• High torsional defl ection• Easy installation• Versatile application potential - fractional horsepower

couplings are available in a range of sizes to permit matching a specifi c coupling to your application.

• One-piece construction – convenient for small equipment with fractional horsepower requirements. Specifi ed torque rating allows 15° angular defl ection for excellent vibration isolation.

• Multi-directional misalignment accommodation – elas-tomeric fl exibility accommodates misalignments up to 1/32 inch parallel, 2° angular.

• Vibration isolation – low torsional stiffness is achieved with the shear-type fl exible coupling because the rubber is loaded in shear. This allows for low system natural frequencies and excellent driveline disturbances.

• Shock protection – torsional shock loads are attenu-ated by torsional defl ection of the elastomer. Torsional fl exibility smooths out rotational disturbances and protects system components from early fatigue failure.

• Noise reduction – no metal-to-metal contact; elasto-meric barrier reduces gear noise, transmission and motor hum between shifts.

• Maintenance-free – elastomer fl exibility accommo-dates all motion without metal-to-metal wear, elimi-nates the need for lubrication.

• Long service life – Dynafl ex Shear-Type Couplings have proven themselves under demanding service conditions. Elastomers resist effects of abrasive mate-rials, oil and grease.

• Attachment – shear-type fl exible couplings are avail-able in an assortment of bore sizes. Refer to Table 1.

• Constant velocity – inherent design properties produce a rotational constant velocity.



Notes: Maximum recommended misalignment - 1/32 inch parallel, 2° angular.

Dynafl ex® Bushing-Type CouplingsRated: 10 to 600 hp at 2000 rpm

LORD Dynafl ex® Bushing-Type Couplings accommo-date misalignment, cushion torsional shock, and do not generate or transmit noise. Since relative motion is taken in the elastomer rather than sliding metal surfaces, no lubricant is involved or ever required. Dirt and grit cannot effect the coupling bushings. The elastomer has been compounded to provide long service life.

Typical applications include driveline installations where multi-directional misalignment must be accommodated and torque loads are medium to high.

Specifi cation, selection and dimension information provided on the following pages facilitate design of the coupling assembly. The bushings are standard parts, and the fl anges can be supplied by the end user or by LORD as a special design.



Selection GuideCompression bushing-type couplings are assembled by pressing the elastomeric bushings into sockets of a coupling fl ange. Once assembled, the coupling can be used two ways:

• Parallel Arrangement The driving shaft can be connected to all of the bush-ings, and the driven shaft connected to the coupling fl ange. This arrangement loads all bushings in parallel and produces maximum torque capacity and a less resilient coupling.

• Series Arrangement This arrangement requires an even number of bush-ings per fl ange. Mating fl anges of the driving and driven shafts are attached to alternate bushings. This arrangement transmits the torque through the bush-ings in an N x N series arrangement, thereby making the torque capacity one-half of the parallel arrange-ment. The coupling is also more fl exible.

When high torque and small space are the control-ling factors, the parallel arrangement is recommended. When misalignment is the controlling factor, the bushings should be applied in series arrangement.

Table 1 provides selection criteria for parallel arrange-ment, Table 2 provides data for the series arrangement. Bushing selection is dependent upon torque require-ments, angular, parallel and axial misalignments, as well as bolt circle diameter, number of bushings and bushing size. The torque values shown on the charts are nominal. The bushings are capable of withstanding higher torques due to the shock loads or other short duration surges.

Torsional FlexibilityBushing-type couplings are relatively stiff torsionally compared to other elastomeric couplings. The torsional spring rate of a coupling assembly can be calculated by using the equation and data provided on the curves.

ExampleRequired torque capacity – 3400 lb-in

Misalignment – Angular – 1.75° Axial – 1/8 in Parallel – 1/32 in

Dynafl ex® LCR Series CouplingsRated: 4 to 135 hp at 2000 rpm

LORD Dynafl ex® LCR Series Couplings are ring-type couplings developed to overcome numerous torsional problems associated with vehicular and industrial driv-eline systems. These easily installed couplings reduce noise transmission and increase bearing and driveline life through greater misalignment accommodation, isolation of low frequency disturbances, and isolation of torsional shock.

These highly fl exible elastomeric couplings for acces-sory drives are also designed to eliminate lubrication and maintenance.

Features and Benefi ts• Misalignment accommodation – elastomeric fl exibility

allows for large angular misalignment. For permissible misalignments, including axial and radial, Refer to Table 1.

• Vibration isolation – low torsional spring rate is achieved with the elastomeric ring-type coupling using rubber in compression. This allows for low system natural frequencies and isolation of fi rst mode driveline disturbances in most driveline systems.

• Shock protection – isolates torsional shock, prevents backlash and protects system components, including bearings, from fatigue failure.

• Long service life – Dynafl ex LCR Series Couplings have proven themselves under demanding service conditions.

• Maintenance-free – elastomer fl exibility accommo-dates all motion without wear, eliminates the need for lubrication.

• Noise reduction – no metal-to-metal contact; elas-tomer attenuates structure-borne noise and isolates vibration from components that would act as noise generators.

• Systems Engineering – LORD has in-house computer capabilities for multi-torsional analysis to assist in proper coupling selection.



Typical ApplicationsDynafl ex LCR Series Couplings are useful for a wide range of rotary drive applications, from lawn and garden tractors to large construction equipment, including U-joint replacement. Typical applications include:

Typical End Product Application

Farm Tractor Trouble-Free Hydraulic Pump Devices

Lawn & Garden Tractors Maintenance-Free Main Drive Couplings

Dynamometer Protects Driveline from Failure

Snowmobile Reliable Main Drive Coupling

Vibratory Rollers Absorbs High Torsional Shock Loads in Eccentric Drive Units

On- & Off-Highway Isolates and Protects Vehicles Auxiliary Driveline Systems

Industrial Machinery Provides Inexpensive Coupling for Maximum Angular Misalignment and Vibration Control

Agriculture Equipment Replaces Conventional Universal Joints and Provides Torsional Flexibility

Dynafl ex LCR Series Couplings were designed and developed by LORD and have been in service since the early 1960s. The basic concept was intended for specifi c applications requiring low-cost, fl exible couplings to accommodate all forms of misalignment and provide torsional resilience.

The coupling design incorporates metal inserts bonded in an elastomeric ring, which loads the fl exing element in compression to transmit torque. Misalignment motion is accommodated by defl ecting the elastomer in shear, which allows extreme misalignment without high reaction forces.

They are ideally suited for light-duty elastomeric universal joints, particularly where noise reduction or shock attenu-ation is required.

Absence of metal-to-metal contact through the coupling eliminates the need for lubrication and maintenance, while also reducing noise transmissions. Installation is accomplished by insertion between simple parallel fl anges. This lightweight coupling element can be arranged in a single or double series confi guration to match specifi c torsional stiffness and misalignment requirements.

Static Load Defl ection Characteristics of LCR-300-600-046A Reference CurveRing-type couplings isolate torsional vibration and reduce the harmful effects of torsion shock. Torsional resilience is one important characteristic. Figure 1 shows the torsional spring rate.

Accommodating axial misalignment along the axis of shafts without high reaction forces is a unique feature of ring couplings. Figure 2 shows this load defl ection relationship.

Ring-type couplings accommodate parallel misalign-ment with relatively low radial reaction forces imposed on driving and driven equipment. Figure 3 shows typical radial load defl ection curves. Load defl ection charac-teristics for other LCR couplings are available upon request.

Specifi cationsMaterials: The elastomer used in Dynafl ex LCR Series Couplings is high-quality natural rubber, which meets LORD specifi cations (available upon request) and exceeds SAE standards. Natural rubber is used because of its excellent physical properties such as tensile strength, tear and abrasion resistance, fatigue resistance and low temperature characteristics. Other elastomers are available to meet special applications needs. The elastomer-to-metal bonds are even stronger than the elastomers.

Dynafl ex LCR Series Couplings listed on the following pages have aluminum alloy inserts. Many other insert confi gurations are possible to meet attachment requirements.

Environmental: Ring-type couplings will perform satis-factorily when exposed to the normal fl uid, temperature and other environmental conditions found in drive-line systems. Special oil-resistant elastomers can be provided where total or partial oil immersion is necessary. For operation in ambient temperatures exceeding 170°F (77°C), consult LORD Engineering.

Misalignment: Misalignment capability applies for speeds up to 3500 rpm. Operation up to 7000 rpm is permitted with reduced misalignment (consult LORD Engineering).

Note: For speeds above 4000 rpm, shielding is required and/or balancing of assembly may be required.

Installation: Normal installation involves simple through bolt attachment to fl anges. For fl ywheel attachment appli-cations, metal inserts can be tapped/counter-bored to permit easy installation.

Remote Driven Units: Multiple U-joint shafts (especially longer shafts) and the speed at which the shaft rotates (especially higher rpm’s) can create complex stability problems. To assure satisfactory coupling performance, all design layouts for remote mounted driven units should be reviewed by LORD Engineering. LORD analytical capability is only one part of the engineering service available on all coupling applications.

LCR ring-type couplings can be selected based on horsepower or maximum torque requirements. The data listed on the next page provides the necessary informa-tion to select a coupling and design it into your system.

New equipment designs and retrofi ts involving recipro-cating engine drives and unusual driveline arrangements should be analyzed to avoid potential vibration and misalignment problems. Contact LORD Engineering for assistance.

Figure 5 – Single Coupling Arrangement Figure 6 – Double Coupling Arrangement

Single coupling arrangement consists of two shafts jointed by a single coupling for maximum economy.

Double coupling/series arrangement uses two couplings separated by a fl oating shaft. This provides same torque capacity as single hub arrangement, with twice the permissible angular misalignment and half the torsional stiffness. Superior to single coupling for control of torsional vibration.



Dynafl ex® LCD Series CouplingsRated: 75 to 2000 hp at 2000 rpm

LORD Dynafl ex® LCD Series Couplings have been developed to overcome numerous torsional problems associated with vehicular and industrial driveline systems. These couplings increase equipment life by protecting against torsional vibration, shock and misalignment.

Typical application attachments include:• Flywheel to shaft• Flywheel to hub (splined)• Shaft to shaft• Floating shaft

Features and Benefi ts• Protection from torsional shock loads• Design fl exibility• Safe for occasional severe overloads• Vibration isolation – extremely low torsional spring

rate is achieved with the Dynafl ex LCD Series Coupling, using elastomer in shear. This allows for low system natural frequencies and isolation of fi rst mode driveline disturbances.

• Damping at resonance – the elastomer used in Dynafl ex LCD Series Couplings effectively reduces vibration at resonance.

• Shock protection – torsional shock loads are attenu-ated by large shear defl ection of the elastomer. In the case of severe overloads, equipment damage is prevented by slippage between the elastomer and the outer housing.

• Misalignment accommodation – elastomer fl exibility allows for angular, parallel and axial misalignment.

• Long service life – Dynafl ex LCD Series Couplings have proven themselves under demanding and rugged service conditions.

• Maintenance-free – elastomer fl exibility accommo-dates all motion without wear, eliminates the need for lubrication.

• Noise reduction – no metal-to-metal contact; elas-tomer attenuates structure-borne noise and isolates vibration from components that would act as noise generators.

• Attachment – fi ts many standard SAE fl ywheels.• Design fl exibility – standard rubber molds are used

to produce each different size coupling shown in this catalog. Often it is necessary to change metal components for custom applications. This is common.

• Systems Engineering – LORD has in-house computer capabilities for multi-mass torsional analysis to assist in proper coupling selection.



Standardization of Proven ConceptUsing the experience gained in designing and producing special Dynafl ex couplings, LORD has developed a new standard product line of heavy-duty Dynafl ex couplings. These couplings have a specially designed elastomeric element bonded to a metal inner member which is then preloaded and friction-fi t into an outer member.

This unique concept provides low torsional spring rates which effectively isolate critical vibratory disturbances in driveline and accessory systems, thus prolonging equip-ment life. Misalignment and torsional shock loads are absorbed by shear defl ection in the elastomeric element.

The ability of the coupling to slip at the outer member with short duration shock overloads protects the drive-line and accessory components from premature failure. The Dynafl ex LCD Series Coupling has been particularly successful for diesel driven applications.

Dynafl ex LCD Series Couplings are available in 75 to 2000 hp ratings at a nominal 2000 rpm. Each size is also available in two stiffness values. These are referred to as the A and C stiffness values. The C stiffness parts are normally stocked.

Load Defl ection DataFigures 1 through 3 illustrate the torque or load versus defl ection characteristics for the -A and -C stiffnesses of the LCD-0400 size couplings. The general characteristics of these curves are typical for all Dynafl ex LCD Series Couplings.

Figure 1 shows the linearity of the coupling spring rate at (and well above) the rated capacity of 12,500 lb-in torque. The curves also demonstrate the unique overload slip characteristic at about 60,000 lb-in torque. It should be noted, however, that the overload protection results from slipping of the coupling. This slipping generates heat, and therefore continuous running at overload could be injurious to the coupling.

Figures 2 and 3 illustrate the fl exibility of Dynafl ex LCD Series Couplings to accommodate axial and radial misalignment. The -A variation is made in a softer elas-tomer to produce a lower torsional spring rate and there-fore had the lower axial and radial spring rates. All spring rates are ideally linear over the normal operating range of defl ection.

Dynamic Torsional Stiffness, KThe dynamic torsional stiffness is higher than the static stiffness at room temperature. When the LCD Series Couplings are attached to diesel engine fl ywheels, the elastomer gets warm. At an operating temperature in the 170° to 200°F range, the dynamic stiffness is nearly the same as the static stiffness at room temperature. The stiffness values shown in the performance characteristics chart are for computer modelling and in other types of torsional analysis work.

Static Load Defl ection Characteristics of LCD-0400-01-A & -C and LCD-0400-04-A & -CCurves of other LCD parts show similar characteristics and are available upon request.

Typical ApplicationsDynafl ex LCD Series Couplings are useful for a wide range of rotary drive applications, from off-highway truck drivelines to auxiliary compressor drives on diesel loco-motives. The soft torsional stiffness of these couplings makes them ideally suited for diesel applications with remotely mounted driven components. Typical applica-tions include:

Typical End Product Application

• AccessoriesStarters Fans and BlowersAlternators Power Take-Offs



Selection GuideThis selection guide can be used to determine the size and series coupling to suit your general requirements. Final selection of the specifi c coupling to satisfy all of the application requirements generally necessitates a system engineering analysis. These computerized analyses of torsional systems can be provided by LORD Corporation’s Engineering Department.

Prolonged exposure to temperatures in the 0°F range and below produces a signifi cantly reduced slip torque prior to driveline warm-up. This condition may result in the coupling’s inability to transmit adequate drive torque for applications experiencing unusual cold temperature related parasitic loading.

Blind assembly style with a notched periphery provides trouble-free, sliding assembly on fl ywheel drive pins when bolted access is not possible. Outer member is a composite material.

Use Wood’s Sure-Grip® Bushing type SK or equivalent.

Dynafl ex® LCD Series Couplings Installation GuideSpecifi cationsMaterials: The elastomer used in the Dynafl ex LCD Series Coupling is a high-quality natural rubber which meets LORD specifi cations (available upon request) and exceeds SAE standards. Natural rubber is used because of its excellent physical properties, such as tensile strength, tear and abrasion resistance, fatigue resistance and low temperature characteristics. The elastomer-to-metal bonds are even stronger than the elastomers.

Standard LCD catalog parts are all made in two stiff-nesses of natural rubber. The A elastomer is per LORD Spec MAP092, having a durometer of approximately 45. The C elastomer is LORD Spec MAP094, having a durometer of approximately 57. The metal parts for this series are of alloy steel or ductile iron.

Environmental: Extensive experience with similar parts indicates that heavy-duty Dynafl ex couplings will perform satisfactorily when exposed to the normal fl uid, temperature and other environmental conditions found in driveline systems. For operation in ambient temperatures exceeding 170°F (77°C), consult LORD Corporation. Dynafl ex LCD Series Couplings are often recommended for use in applications where the temperature is above 170°F (77°C). Temperatures above 200°F (93°C) could present problems. Customers should know what the ambient operating temperature is and whether addi-tional air circulation can be provided. Consultation with LORD Corporation engineers is necessary if the ambient temperature is above 170°F (77°C).

Misalignment: Misalignment capability applies to speeds up to 2500 rpm. Operation up to 3500 rpm is permitted with reduced misalignment. (Consult LORD when a potential application requires special consideration).

At normal rated operating conditions, the Dynafl ex LCD Series Couplings are designed to accommodate misalignment.

Angular: 1-1/2° maximum Parallel: 1/64 inch Axial: +1/16 inch dynamic +1/8 inch static

Testing/Performance: Periodic load defl ection tests are run to assure consistency of torsional spring rate and slip torque characteristics.

Damping Coeffi cient, C: The natural rubber elastomer used in LCD couplings offer hysteresis damping which dissipates energy at resonance.

The “damping coeffi cient” is a function of many vari-ables. Among them are dynamic strain, frequency, elastomer type and stiffness, temperature and torque loading. Damping coeffi cients for this series have been determined and can be provided for torsional analysis work by contacting LORD.




This arrangement must not be used. Suitable bearing supports are required to react cardan-induced cocking loads. Consult LORD Engineering for application review.

InstallationFor engine applications, the outer member is usually bolted directly to the fl ywheel; for other applications, to a suitable adaptor. The inner member normally attaches to the driven shaft. The smaller LCD couplings generally have a tapered bore, which accommodates a standard split tapered bushing which grips the drive shaft. (Refer to Table 1 - Split Tapered Bushings). This confi guration provides easy installation.

Figures 15 and 16 on the next page show typical installations involving universal joints.

Dynafl ex® LCD Series Couplings Torsional System Analysis Input RequirementsDynafl ex couplings offer unique advantages with the soft torsional spring rate that isolates torsional vibration, mitigates shock and reduces noise transmission. In order to benefi t from these advantages, an analysis must be made of the application and a coupling selected which meets the specifi c requirements. The following checklist sets forth the information required to initiate the analysis:

Application Data• What is the driving unit, driven unit? Include enough

information to determine disturbing frequencies (e.g., type of engine, number of cylinders, number of cycles).

• What is the operating torque (normal, maximum)?

• What is the operating speed (range, at normal torque and at maximum torque)?

• What are the environmental conditions (temperature, oil type and amount of exposure, corrosive factors, other factors)?

Coupling Requirements• What are the primary functions of the coupling

(torsional vibration isolation, torsional shock mitigation, noise attenuation, shaft misalignment accommodation – angular, parallel, axial)?

• If known, what torsional spring rate should the coupling have?

• If the required torsional spring rate is not known, what are the rotational moments on inertia of the driving and driven masses?

• How much misalignment must the coupling accommodate (angular, parallel, axial)?

• How much, if any, axial thrust will be on the coupling?

Design Parameters• What space is available for the coupling (maximum

length, diameter)?

• What is the maximum weight the coupling can be, if weight is limited?

• What are the shaft diameters and method of attachment (keyway, spline, set screws, fl ange)?

• What special features are required? (Inner member design – hubs, fl anges, splines, etc. Outer member design – pilot diameter bolt pattern, etc.)

Remote Driven UnitsMultiple U-joint shafts (especially longer shafts) and the speed at which the shaft rotates (especially higher rpm’s) can create complex stability problems. To assure satisfactory coupling performance, all design layouts for remote mounted driven units should be reviewed by LORD Engineering. LORD analytical capability is only one part of the engineering service available on all coupling applications.

What Else? If your application is unique or unusual, include any information that you believe will have an effect on the coupling design or selection. If you have any questions as you prepare this data, call us. See following page for data form.
